Specification of Letters Patent.

Application filed November 1,1905. Serial N0. 285.?07-

To u/ll whom it may concern.-

Be it known that I, DECATUR D. DENNIS, a citizen of the United States, residing at Prosser, in the county of Benton and State of Washington, have invented or discovered certain new and useful Improvements in Water- Elevators, of which the following is a specification, reference being had therein to the accompanying drawings. v

This invention relates to that class of water-elevators in which the lifting elements are carried by endless chains driven by sprocket-wheels; and the invention has for its object to provide a water-elevator of this class which will be of such construction that spherical elevating elements or buckets may have a close-running fit in the tube'or cylinder through which the water or other liquid is lifted and which spherical elevating elements or buckets will be so fitted to the sprocket-wheels and so connected with the chains that the whole apparatus will run smoothly when in operation, and will also be so constructed as to be capable of rapidly lifting a very large quantity of liquid.

To this end the improved apparatus comprises two sets of sprocket-wheels and two chains, which latter are attached to the spherical elevating elements or buckets within the lateral peripheries of the latter, so as to run clear of the interior walls of the lifting tube or cylinder, the said sprocket-wheels being suitably recessed so as to receive the spherical elevating-buckets and said wheels being beveled or chamfered off at the edges of the said recesses, so that the buckets or elevating elements will fit closely against the same.

In order that the apparatus may be suitably driven by power, if desired, the shaft carrying the upper sprocket-wheels is preferably provided with a worm-wheel which meshes with a worm on a suitable drivingshaft.

In the accompanying drawings, Figures 1 and 2 are vertical sectional views at right angles to each other of an apparatus embodying the present invention. Fig. 3 is a horizontal section on line 3 3 of Fig. 2, and Figs. 4 and 5 are detail side and sectional views, respectively, of one of the sprocket-wheels. Figs. 6 and 7 are side and sectional views, respectively, of one of the spherical elevatingbuckets, and Fig. 8 is a detail view to be referred to.

Referring to the drawings, 12 denotes a tube or hollow cylinder to which may be attached in any suitable manner brackets 13 for supporting theupper and lower shafts 14 I and 15, to which the sprocket-wheels 16 are suitably fixed. The sprocket-chains 17 are suitably connected to spherical elevatingbuckets 18, the said sprocket-wheels being provided with recesses 19 to receive the said tached to the spherical elevating-buckets 18,

the latter are preferably provided with screwstuds 2 1, having eyes 22 or hooks 23, by means of which the ends of the chains can be connected to the said buckets, or instead'of using the said screw-studs provided with hooks or eyes links 24, (see Fig. 8,) having suitable eyes or hooks, as 25 and 26, may be employed, the said links passing through the said spherical buckets.

Attached to the tube 12 is a guideway 27, preferably having a central rib 28, against which the buckets may run, said rib serving to steady the said buckets as they descend.

To enable the apparatus to be driven by power, the upper shaft 14 is preferably provided with a worm-wheel 29, meshing with a worm 30 on a driving-shaft 31, said shaft being supported in a suitable bracket or brackets 32. If, however,'it be desired to turn the pump by hand, elther the worm-wheel or worm may be disconnected and a suitable hand-crank 33 (indicated by dotted lines) be employed for driving the pump.

From the foregoing it Wlll be apparent that the invention provides a water-elevating apparatus employing spherical lifting buckets or elements, which are connected with two chains, so that much more power may be applied for the purpose of lifting a larger body of water than would be the case if only a smgle chain running over one set of sprocketwheels were used, while the construction described provides means whereby the spherical elevating buckets may be suitably steadied against the sprocket-wheels when passing over the same, thus enabling the whole apparatus to run strongly and smoothly and. without being liable to noise and jerks which might otherwise occur.

Having thus described my invention, I claim ankl .desire to-secure by Letters Pat'- ent 1. Aliquid-elevating apparatus comprising the combination witha suitable tube, of

I spherical elevating elements or buckets closely fitting said tube, two shafts, two sprocketwheels carried by each of said shafts and suitably recessed for the reception of the said spherical elevating elements or buckets, said sprocket-wheels being chamfered or beveled at said-recesses to permit the said elements or buckets to fit closely in their sockets, and two chains running over said sprocket-Wheels and connected with'said spherical lifting elements or buckets.

2. A liquid-elevating apparatus comprising the combination with a suitable tube, of

and connected with said spherical lifting elements or buckets, each of said buckets being provided, within its lateral periphery, with suitably recessed for the reception of the said spherical elevating elements or buckets, said sprocket-wheels being chamfered or beveled at said recesses to permit the said elements or buckets to fit closely in their sockets, and two chains running over said sprocket-wheels and connected with said spherical lifting elements or buckets, each of said buckets being provided, within its lateral periphery, with means for the attachment of the said chains, said means comprising threaded studs provided with suitable hooks or eyes for engagement with the said chains.

In testimony whereof I affix my signature in presence of two witnesses.

DECATUR D. DENNIS.
